How do you seal plastic threaded pipes?
Wrap tape in a clockwise direction around the threads. The only approved sealant for plastic (PVC/CPVC/ABS) threaded connections is PTFE (Teflon®) tape. The tape must be applied such that it wraps tighter around the threads as the connection is being tightened. The easiest way to tape threads is if you’re right handed.
